Nicotine Shots (sometimes known as shake n' vape kits) are 10ml bottles of flavourless e-juice which contains 18mg of nicotine and which can be added to any nicotine-free e-liquid. Shortfills are 60ml bottles of e-liquid containing no nicotine which only contain 50mls of e-juice, leaving sufficient space to add the nicotine shot.
